Today’s newspaper was riddled with insults and accusations about who ‘liked’ or ‘shared’ various posts on Facebook. To paraphrase, one read ‘that a board member of x [any board or agency or organization] has “liked” or shared social media posts about y [any controversial topic] by z [any controversial figure].’ How could they?
Months ago, for example, I received an email from a neighbour saying she could not believe that I had “liked’ a post by one of my old colleagues. I replied that I found his post to be engaging and stimulating – worth reading, but I did not ‘agree’ with his views.

There are at least two problems with this kind of oversight.
First, to like a post on Facebook does not mean that you agree with it in whole or in part. It could mean that you noticed it, recommended it to others, disagree, or really, it could mean just about anything. For me, a ‘like’ is a general acknowledgement that you had read or have seen the post, as if saying thank you for posting. For example, liking a photo someone posts might simply be a way of saying hello to them. There is no unlike button. Anyone who assumes that a ‘like’ means you agree is simply wrong much if not most of the time.
A parallel example is when Americans or Europeans visit Japan, they often translate the common Japanese response of “Ah So” – short for ā sō desu ka – to mean the speaker agrees, or is saying “yes”. My Japanese friends tell me it essentially means that the speaker ‘understands’, as in ‘ah, I hear you’. Often, in fact, it implies ‘no’ – not ‘yes’, as it is so impolite to say no. [Correct me if I’m wrong.]
So, in a similar way, it is wrong to assume that a ‘like’ means agreement. If everyone understood this, there would be a lot fewer disputes in the newspapers and online. Many more emojis have been added to online media, but I would not count on the greater choice of emoji settling the issue. What does that wink mean?
The second problem is that I wish my friends, neighbours, or Facebook friends would not make assumptions about my beliefs or opinions based only on such a crude signal as whether I like or share a post. It is a type of social pressure or sanction that can have a chilling effect on me and perhaps on other speakers. If I start thinking that I will be judged by what I ‘like’ – not on what I actually say – then I will stop ‘liking’ anything. Better to say nothing than to be misunderstood. I don’t mind it if I am confronted, such as by my neighbour, as then I can explain myself, if I wish to, and thank them for asking. But one can only assume that too many people draw unwarranted conclusions without testing them with you. Did you mean that you agree with that post?
Given the directions of technical advances, in due course, you might know what I look at or read, even if I don’t react to the post. “You ordered that book?’ ‘You looked at that person’s profile?’ So this kind of problem could get far worse.
Let me apologise to you, if you’ve been critical of my – or anyone’s – ‘likes’. But as they say, apologizing does not mean that I am wrong, but that I value your friendship more than proving myself right. By the way, I have very few “friends” in real life, but many “Facebook friends” – they are not the same thing, so should we all try harder to be as aware of online conventions and the meaning of terms used online, just as we try to keep up with the nuances of speech in general?
